About the company

Energy generation from fusion

Fusion will be one of the greatest breakthroughs of this century. Proxima Fusion is working to develop power plants via optimized stellarators, devices that form magnetic cages for high-energy matter. Proxima is the first-ever spin-out company from the Max Planck Society Institute for Plasma Physics, which built and operates the most advanced stellarator on the planet, W7-X. Research over the past decade has now set the stage for Proxima to leverage modern optimization tools and design capabilities, and accelerate fusion. With W7-X reaching high-performance in continuous operation, uniquely among fusion concepts, Proxima Fusion is catalyzing the creation of a new fusion ecosystem in Europe. Connecting partners from industry and academia, the Proxima Fusion founding team, coming together from the Max Planck Society, MIT and Google, is now entering the race for fusion energy to turn stellarators into economically viable fusion power plants.
